Current ideas of the uses of Model Organisms spring form the exemplars of the past and choosing the right organism for one's research is as important as finding the right problems to work on. In all my research these two problems have been closely intertwined.

A lot of the things that have been accomplished in science have been accomplished on the basis of ignorance … in the sense that you import into the science people from outside. Because once you have an established science, it has got its high priests — the guys who know everything that will work or won't work. And they don't want to be bothered. So you have to have a challenge. And the great thing is that young people are ignorant, and we should catch them before they turn into the priesthood. So I think that science should have a much more daring approach.
